Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Sauce for Salmon and Other Fish
Ingredients
Directions
Heat the milk in a saucepan until it boils.
Mix the cornstarch with cold water to form a slurry, then add it to the boiling milk to thicken.
Stir in the butter and the liquor from the salmon.
Remove from heat and add the beaten egg, stirring well.
Season with mace and cayenne pepper, then let it sit in hot water for 3 minutes, covered.
Finally, stir in the lemon juice and serve immediately over the salmon.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce that thickens into a creamy body.
- Cornstarch
- Thickens the milk as its starch swells when heated in liquid.
- Raw egg
- Adds richness and helps set the sauce slightly as it is stirred in off heat.
- Butter
- Adds fat for a smooth, rich mouthfeel and flavor.
- Lemon juice
- Adds acidity that brightens the flavor of the rich sauce.
The step that matters
Adding the beaten egg off the heat. Egg proteins set at higher temperatures and can curdle or scramble if the sauce is still boiling. Removing it from the heat and stirring well keeps the sauce smooth.
Swap the mace
How well each one fits the dish's main ingredients (milk, butter, egg, lemon, pepper):
- Parsleyfits better
- Nutmegfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against milk, butter, egg, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
